Question regarding DBS Antennas

I recently purchased a Phantom 3 Advanced. Previously I had a Phantom 2 Vision Plus with the ITELite antenna.

My question for DBS (or anyone else) is if I connect the two 2.4ghz panels from the Phantom 2 antenna to the Phantom 3 remote, will I get similar performance to the new Phantom 3 version ITELite antenna, or is the new antenna very much improved in the 2.4ghz area?

As I understand it, the old Phantom 2 antenna had 1 x 5.8ghz panel and 2 x 2.4ghz panels.

This is the antenna I already have. It was designed for Phantom 2 Vision+
It has 1 x 5.8GHz antenna for control and 2 x 2.4GHz antennas for the Wi-Fi vision connection.drone-antennas

This is the Phantom 3 antenna I was considering. It has 2 x 2.4GHz antennas. Due to the package size I'm guessing the 2.4GHz antennas may be larger inside the white case.drone-antennas

I didn't know there was a MAXX range until you mentioned it. The larger size of the panel suggests excellent range probablities.drone-antennas

My initial question was: Would the 2 x 2.4GHz panels inside the Phantom 2 version be in any was suitable for the Phantom 3 Andvanced. Has anyone tried using this panel on the Phantom 3? Or should I just be saving my pennies for a panel specifically designed for the Phantom 3? My current range in CE mode is no better than my Phantom 2 Vision+
